[Mingw-users] iostream and multiple threads

[The C. <Th...@gm...>]

hi, i've got a problem concerning iostreams.

i need a threadsafe log for my program. as far as i know the stl should be
threadsafe, but it isn't. when i create several threads which only repeat
printing out a message using cout, the output is pretty messed up. it seems
as if a thread prints his message while an other one is doing the same.

are there some switches to consider? i used mthreads without success. or do
i need to derive my own threadsafe streambuf?

thx thecom
